It looks just the same. The main ongoing work is all under the hood: large conceptual changes how time is represented (musical time, midi notes & looping) and signal flow (allow cue monitoring, latency compensation). "What is it like?" still mostly broken at this point in time.

Chances are that the GUI (look & feel) will not change at all for 6.0 (perhaps later in the 6.x cycle). 6.0 is predominantly a major overhaul of the backend to fix some long standing bugs and implement some long standing missing features...
